HARROW.

SPE'GIFIGATION forming part of Letters Patent N0. 254,017, dated February 21, 1882.

I Application filed December 10,1881. (N0 model.)

T0 all whom a't may concem Be it known that I, GE.0. JACKSON, 0f Boscobel, in the county of Grant; and State of Wisconsin, have invented certain new and useful Improvements in Harrows; and I d0 hereby declare the following t0 be a full, clear, and exact; description of the invention, such as will enable others skilled in the art to which it pertains t0 make and use it, reference being had t0 the aecompanying drawings, which form part 0f this specification.

My invention relates b0 an improvement in harrows; and itconsistsin the combination 0f four sections, eaclx one of which is composed ofanumber of parallel beams which are placed equal distances apart, and which are united together by means 0f rods whieh pass diagonal] y through the ends of adjoining sections, the beams being so arranged that the ends of 110 two of the beams will come together, as will be more fully described hereinafter.

The object 0f my invention is to provide a harrow whieh can be turned up from any one corner, and which is adapted to be pulled from any one corner o1 side equally as wel], without the necessity of any changes, with the exception of the deviee to which the draftchains are t0 be fastened.

Figure l is a plan view 0f rny invention, partly in section. same'showing one-half 0f the harrow turned up at one coruer.

A represents four separate and distinct sections ofthe harrow, eaeh one ofwhich is fonned of the thr'ee beams B, which are placed equul distances apart. The beams of any one section are made the same length as the corresponding section which is made opposite to it, and in which case the beams are secured rigidly together by means of the brace-rods D, which are secured across theix tops. These four sections am attached loosely together by means of the pivotal rods E, which are passed diagonally through their corners, each rod passing ab an angle through the end of each beam of both sections. The outer ends of these rods am hooked 0r bent backward in any suitable 1nanner, und the inner ends of the r0ds are passed through washers 0r shoes H, which are made 0f iron am1 seeured to the inner beams of the two seetions which have the shortest inner beams. In order 130 prevent the inner ends of I;he rods from being pulled out- Fig. 2 is an edge view 0f the ward through the washer, pins or stops of any kind may be applied to the rods, as shown.

Each corner of the harrow will be provided with two holesone in each adjoining seotion in which suitable staples or holding b01lss will be placed, and 110 these staples or bolts will be fastened a suitable draft-chain; This draft-clxain can be transferred from one corner t0 the other of the harrow, and thus enable the harrow to be drawn equally well from eaeh one of its four corners.

As the pivotal rods pass loosely bhrough the ends 0f the beams of each section -these rods form a pivot upon which any tw0 0f th.e sections can be raised upward from any one of its four corners, as shown in Fig. 2.

II; will .be not-iced that the beams .are arranged in such relation 130 eaeh other that the end of no one beam comes in contact with tl1e end of another beam, but that the ends are all placed at equal distanoes apart, as shown, so thal: the pivotal rods will pass through the end of each beatn alike. While the ends of these beams (10 not; come together, the end of each beam bears againsb the edge 0f another beam, and the parts am thus braced together while in operabion withont in any manner interfering with their foldin g movement.

As the harrow is drawn along, in case an obstruction is encountered the ha1row will give equallyalike at any point. Should the obstruct-ion be just in a line with the center 0f the harrow tl1e harrow will rise upward a1: the

cener, so as 130 pass over in; but should. the

seebions, A, each one 0f which is composed 0f 9 5 a number ofbeamsor bars, B, ofunequal length, with the pivotal 'rods E, whieh pass diagonally through the ends 0f the beams, substantially as shown.

In testaimony whereof I affix my signature in presence of two witnesses.
